Abstract

The invention proposes a municipal cleaning vehicle for flushing and cleaning sewers and vessels or the like, comprising a tank (10) having a sludge compartment (11) and a service-water compartment (12), it being possible to connect said service-water compartment (12) to a flushing hose (14) through which, by means of a pump device (15) which is upstream of a pressure-regulating valve (17), water (19) is delivered to that end of the flushing hose (14) which may be provided with a nozzle head (16). The pressure of the water (19) between pump device (15) and the pressure-regulating valve (17) is registered, an assembly (18) which drives the pump device (15) having its drive efficiency reduced in the event of an increase in pressure beyond a presettable pressure of the water (19). <IMAGE>
